Tulips by cultivar and division for cut flowers

Tulips are easiest to plan when you treat each name as a set of facts: a cultivar, a horticultural division, a colour, and a season. Ad Rem, Angelique, Black Parrot and Apricot Beauty each sit in a different group and open at a different point in spring, which is why two beds planted on the same weekend can look empty and full a month apart. If you are choosing bulbs for a farmhouse garden or for cut flowers, the practical move is to read the division first and the colour second, because the division tells you when the flower arrives and how it holds up.

What do the horticultural divisions actually tell you?

The divisions are the working language of the tulip trade, and they group cultivars by flower shape, parentage and flowering period. Double Late types carry heavy, many-petalled heads and close the season. Lily-flowered tulips have narrow, pointed petals that curve outward. Rembrandt types show broken, streaked colour. Viridiflora cultivars keep a green stripe through the petal. Parrot tulips are ruffled and fringed at the edge, while Fringed types carry a fine crystalline border. Triumph tulips are the mid-season workhorses, Single Early types open the season, Darwin Hybrids are tall and long-lasting, and Species tulips are the small, wild-looking originals that naturalise in grass.

A gardener who compares names before planting can use this list as a calendar. Single Early and Species flower first, Triumph and Darwin Hybrid follow, and Double Late, Parrot and Fringed bring up the rear. The same list also predicts how a stem behaves in a vase: Darwin Hybrids and Triumph hold a straight line, while Parrot and Double Late heads are heavier and may need support in wind. For a fuller reference on groups, colour and season, the notes at tulip cultivars and divisions set out the divisions one by one.

Ad Rem, Angelique, Black Parrot and Apricot Beauty: what sets each one apart?

Ad Rem is a Darwin Hybrid, and that placement matters more than its colour. Darwin Hybrids are tall, with large flowers on strong stems, and they tend to return for more than one spring if the foliage is left to die back. Ad Rem carries a warm orange-red flower with a yellow base, and it opens in mid-season, between the early singles and the late doubles.

Angelique is a Double Late tulip. Its flower is a soft pink, fully double, and it looks closer to a peony than to a classic tulip cup. Because it flowers late, it is the one to plant where a bed needs colour after the main flush has gone. The heavy head is the trade-off: in an exposed border, Angelique benefits from a sheltered spot or a low planting of something that breaks the wind.

Black Parrot belongs to the Parrot group. The petals are deep maroon, almost black in shade, with the twisted, fringed edge that defines the group. Parrots are late, and their stems are less rigid than a Triumph, so they read best at the middle or back of a border where the ruffling is visible against a lighter background.

Apricot Beauty is a Single Early tulip. It opens at the front of the season, with a soft apricot-pink flower on a shorter stem, and it is one of the most useful cultivars for a small garden because it finishes before the late types need the space. In a cut-flower patch, Single Early types are the first stems of the year.

How do colour and season work together in a border?

Colour reading is a skill, and tulips teach it quickly because the same pigment looks different at different times of day. A deep maroon such as Black Parrot reads as black in flat light and as wine red in sun. Apricot Beauty shifts between peach and pink depending on the light and the age of the flower. Angelique holds its pink steadily, which makes it a reliable anchor in a mixed planting.

The practical method is to group by season first, then by colour. Plant the early types together so they can be cut and cleared before the late ones rise. Keep the strong colours, the reds, maroons and oranges, in one block, and let the soft pinks and apricots sit beside them rather than among them. A border that mixes seasons in the same square foot will look thin for weeks, because the early flowers finish while the late ones are still in bud.

Border composition also depends on height. Darwin Hybrids and late doubles are tall enough to stand at the back. Single Early types and Species tulips belong at the front, where their smaller scale reads properly. Species tulips in particular are worth a place in grass or at a path edge, since they naturalise and come back without lifting.

When and how should tulip bulbs be planted?

Plant tulip bulbs in autumn, once the soil has cooled, which in most temperate gardens means October and November. The old rule is to set the bulb at about three times its own depth, so a large Darwin Hybrid bulb goes into a hole roughly 15 to 20 cm deep. Space them about 10 to 15 cm apart if you want a full bed, closer if you are planting for cut flowers and intend to lift them.

Soil matters more than feed. Tulips want free drainage, and a wet winter is the main reason bulbs rot. On heavy ground, plant on a raised ridge or add grit to the planting hole. Full sun keeps the stems straight; a site that stays shaded in the afternoon will produce softer growth and weaker stems.

Species tulips are the exception to the lifting routine. They are smaller, they naturalise, and they can be left in the ground for years in grass or at a border edge. Garden tulips, by contrast, give their best flower in the first spring, and many gardeners treat them as annuals and replant each autumn.

How do you care for bulbs after flowering?

Let the foliage die back naturally. The leaves are the bulb's only way to store energy for the next season, and cutting them while they are still green costs you the following spring. Remove the flower head once the petals fall, so the plant does not put energy into seed, but leave the stem and leaves in place.

Water during dry spells while the leaves are green, then stop once they yellow. If the bulbs are staying in the ground, mark the spot so you do not dig into them later. If you are lifting them, wait until the foliage has fully withered, then dry the bulbs in a shaded, airy place and store them in a cool, dry spot over summer.

A simple record helps. Note the cultivar, the division, the date the first flower opened, and how long it held. After two or three springs, that notebook tells you more about your own garden than any general list, because it shows which groups actually perform in your soil and your light.

What should you check before you buy bulbs?

Check the division and the season before the colour. A name alone does not tell you when a tulip flowers or how tall it grows, and those two facts decide where it can go in the garden. Check the bulb size as well: larger bulbs of the same cultivar generally give larger flowers.

Buy from a supplier who lists the cultivar name and the group, not just a colour mix. A mix is fine for a meadow or a wild corner, but for a border plan you want to know that Angelique is a Double Late and that Apricot Beauty is a Single Early, so the planting order holds. Keep the labels, and keep the notes. The garden remembers what the label forgets.
