Plants for (sub)tropical clay soils

I recently posted on the Soils, Mulch and Compost forum asking for suggestions for plants that would grow well in the named conditions. In the end I deided to my own research simply by interviewing a few of our neighbors and viewing their gardens.

Our list, not by any means comprehensive, of ornamental plants suitable for minimally improved tropical and subtropical clay soil is as follows:

Abelmoschus Hedychium (Ginger Lily)

Agapanthus Helianthus

Agave Helianthemum

Aloe Helichrysum

Alstroemeria Hibiscus

Amaranthus Hippeastrum (Amaryllis)

Brugmansia (Datura) Ipomea (Morning Glory)

Buzy Lizzie (Impatiens) Lantana

Camellia (needs some shade) Marigolds (all types)

Canna Mirabilis (4 o�Clock Plant)

Candytuft (Iberis) Nigella

Cleiome Passionflowers (all types)

Cosmos Portulaca

Coreopsis Physalis

Delphinium Ricinus (Castor Oil Plant)

Eustoma (Prairie Gentian) Rudbeckia

Echinacea (Coneflower) Salvia

Frangipani Sanvitalia

Gaillardia Sobralia (Orchid)

Gardenia Sunflower

Gazania Thunbergia (all)

Gourds Venidium

Heliconia (most need shade) Verbascum

Indian Azalea Verbena

Indian Blue Sage (Eranthemum) Zinnia

It seems enough to be getting on with and I haven�t even mentioned trees or vegetables! Don�t worry. There are plenty I have failed with. If it�s not in the list, it�s probably one of them. One I forgot to mention, but they are surprisingly good, are Roses. You must prune them often, however.

One tip I have found very useful. Wherever possible in clay soil sow seeds direct, working in plenty of sand into the drill. The problem occurs immediately after germination when the roots find it difficult to penetrate the dense soil, so give them a good start...and of course don't forget to water!
