- Longwood Gardens is open to visitors year-round where one can walk through its vast outdoor spaces or inside one of its many greenhouses. This is a beautifully planted allée of Japanese elm trees, Ulmus davidiana var. japonica ‘Morton’ – one of the more graceful elms endemic to parts of continental northeast Asia and Japan. Its leaves have already fallen for the season.

This is a Bismarckia palm, Bismarckia nobilis, which grows from a solitary trunk, gray to tan in color, and slightly bulging at the base. The nearly rounded leaves are enormous and are divided to a third its length into 20 or more stiff, once-folded segments.

- Ever see a multi-fingered citrus? I have these in my greenhouse as well. These citron trees are trained with traditional espalier methods. The ancient horticultural technique involves growing trees, shrubs, and vines flat against some kind of support structure to maximize space and create an interesting appearance.
- These espaliered fruits are hybrid kumquats, ‘Fukushu.’

- This Fan Aloe, Kumara plicatilis, has grey stems forked with clusters of round tipped leaves arranged in two opposite rows.
- Another type of Aloe is Soap Aloe, Aloe maculata. This hardy succulent shows off rosettes of thick, lance shaped leaves that are green with white markings. The leaves have sharp eges that turn reddish in color when exposed to intense sunlight.
- This plant is an ivy geranium, Pelargonium peltatum ‘Crocodile.’ It features rough textured green leaves with yellow white veins. Unlike some other geraniums which can handle higher heat and scorching sun, this one prefers some shade cover.
- Hybrid spurge, Euphorbia ‘Miner’s Merlot’ has a lovely deep burgundy color. It is easy to care for and adds mounding texture to the garden.
- Here’s another Euphorbia, Euphorbia esculenta. It is also known as Vingerpol Milkbush, a succulent shrub native to South Africa. It features thick, fleshy water storing stems. and small cascading leaves that produce yellow-green flowers when in bloom.
