Shasta daisies, Hydrangeas, Cosmidium

Plant now note paper

What to plant this week? Pure white shasta daisies, large round-headed hydrangeas (or try the cone-shaped Hydrangea paniculata) and gold and chocolate-coloured cosmidium.

Shasta daisyShasta daisies
Shasta daisies (Leucanthemum x superbum) produce pure white blooms with yellow centres on tall stems. They flower profusely over summer and are excellent cut flowers. Drought tolerant once established, they like full sun and free-draining soil. Look for plants at your local garden centre.

HydrangeaHydrangeas are currently being shipped into garden centres in huge quantities, so if you haven’t already, get one in the ground now. They like a rich, free-draining soil and plenty of moisture, so make sure you provide ample water while their root systems are developing. Flowers and foliage will wilt if water is lacking but they’ll soon perk up once given a drink. Part shade is best, although Hydrangea paniculata tolerates more sun. The mophead hydrangeas (Hydrangea macrophylla, shown here) are the most commonly grown hydrangeas, with their big fluffy balls of pink, blue or white, but Hydrangea paniculata is worth growing too, with its pyramid-shaped clusters of white flowers that mature to pink.

Cosmidium burridgeanum looks like a refined coreopsis with its chocolate centres and gold tips. It’s an easy-to-grow annual, excellent for both the border and the container, and makes a great cut flower. Available from Egmont Seeds.

    Hi, my daughter is getting married in our garden on March 10 2012. If I plant Hydrangea’s now, how long will they flower for please.

    • I’d be surprised if you found hydrangeas in the garden centres in winter. They don’t usually appear until late spring/early summer. However, hydrangea flowers last for a number of months, but bear in mind they do fade in colour in late summer/autumn. That often gives the blooms an ‘antique’ type look, which I love. So for example, if you chose blue flowers, they might fade to a purplely-green by March, or deep pink flowers to a light pink. What you see in spring or early summer won’t be what you get in March.
      Also, choose the mophead (round head) varieties – these are the ones that last. Don’t get a lacecap variety (more of a lacey look than a rounded head). These flowers don’t last long at all.
