Tulip (Tulipa greigii ‘Oratorio’)
Known for being reliably perennial, Tulipa ‘Oratorio’ (introduced in 1952) blooms in midspring and has splayed, flashy maroon-mottled leaves. It is a standout in the garden from the moment the exquisite heavily striped leaves emerge. Its dazzling 14- to 16-inch-tall coral pink flowers are an added bonus.
Noteworthy Characteristics: Greigii tulips is one group made up entirely of plants with variegated leaves.
Care: Grow in fertile, well-drained soil in full or afternoon sun. Use them in containers or raised beds if soil drains poorly. Plant to a depth of two and a half times the height of the bulb. In regions warmer than Zone 8, bulbs will need a cold treatment (40° to 45°F for 8 to 10 weeks).
Propagation: For more bulbs, lift plants in summer and remove the offsets (small lateral bulblets). In fall, replant the bulbs and offsets and fertilize with low-nitrogen fertilizer.
Problems: Bulb and root rot, gray mold, slugs, snails, aphids, nematodes, voles.
