Bromeliads and the Pineapple Family

Bromeliads and the Pineapple Family

Kew 092

Members of the Pineapple family Bromeliads grow in the tropical and sub-tropical forests of the Americas. There are also hot desert and cool mountain varieties amongst this large family.

What Are Bromeliads

  • All 3000 + varieties of Bromeliads are composed of a spiral arrangement of leaves sometimes called a rosette.
  • There are Terrestrial (soil grown plants) and Epiphytic species growing on other plants and trees.
  • They are slow and hard to bring into flower generally only flowering once. After flowering they produce offsets called ‘Pups’ from which new plants will grow.
  • The green, leafy top of a pineapple is a pup that may be removed and planted to start a new plant.
  • Flowers are generally central spikes held away from the plants or short with the flower nestled in the centre.

Gladioli 100 Day Display

Gladioli 100 Day Display

Gladioli

Gladioli are reliable flowers for the show bench or the flower vase. Timing is important for the exhibitionist as they want to have the flowers in peak perfection just at the right time.

Timing can be important for the local grower as well. If you want Gladioli for a particular event, birthday or wedding celebration, then it is useful to know that corms planted now will be in flower in 100 days. That is just over 3 months so by the middle of August you can expect displays like these from a may planting.

<b>

Gladioli Pointers

  • Gladioli have a front and back to the flower with the florets facing the sun. It helps the flower arranger but can frustrate the gardener.
  • Gladioli will twist the flowering stem unless they are supported so it is worth staking your blooms.
  • Leaves are needed to help feed the new corms for next year so leave them on the plant after cutting the flower.
  • Unless you are a keen breeder remove flowers before seed sets to preserve energy. You may get small offsets, cormels, spawn or bulblets to grow on and bulk up next year.
  • Gladioli need lots of water to flower well. Apply tomato fertiliser when flower buds start to appear.
  • I grow blocks of single colours together so they will be ready together.
  • Sorry to disappoint but the flowers will not last 100 days that is planting to blooming time

Growing Corydalis for Colour and Fine Foliage

Growing Corydalis for Colour and Fine Foliage

Cordialis popovii

Corydalis popovii
is a small bulbous plant flowering up to 6 inches in height. In spring it assumes a white colouring after the purple flowers. This plant comes from Central Asia and is easy to grow and long-lived in a well-drained compost in a pot.
They can be grown in the open garden in full sun and freely drained soil.
Fertilize with a specific fertilizer for bulbous plants, every 2-3 weeks, from when the first flowers start withering.
Corydalis plants don’t like cold temperatures or wet conditions and need a rest period before being brought back into growth.

Corydalis wilsonii

Corydalis wilsonii arrived from it’s native china comparatively recently.
It is a compact herbaceous plant with light green leaves.
It flowers on errect spikes, 1″ long, in a deep yellow during late spring.
This variety is suitable for growing in pots.

I have just bought a Corydalis Kingfisher from the local AGS meeting. Kingfisher has blue flowers with a hint of green from March to Aug and is only without flowers when dormant during winter.

Abu Hassan Tulips

To make a bold statement in a garden you can opt for hard features and structures or soft features created by plants and flowers.

I personally err towards the plantsmans view and like plants. However the use of one variety in great abundance can have a startling effect as these Abu Hassan Tulips show.

Sticking to the Arabian theme not everyone can have a centuries old moorish bath in the garden like the featured garden below. The distinctly moorish shapes are replicated through out with the addition of large pots & stands both terracotta and glazed.
