The collection of hardy perennials is one of the largest in the Botanical Garden - it contains 1550 taxa. A particular attention has been devoted to hostas (97 different spcies and cultivars) and geraniums.

Bulbous plants

Many ornamental bulbous plants have dispersed naturally as weed to grass lawns and flower beds of the Botanical Garden. In spring the most frequent bulbous plants in blossom are Galanthus, Leucojum, Chionodoxa, Scilla and Corydalis while Colchicum and Crocus bloom during the autumn. Certain bulbous plant collections have become a great value of the Garden. The Lily Garden has been developed as a special exposition for demonstrating cultivars of lilies (in total 50 cultivars) bred by Ādolfs Zorgevics. Besides, there is a notible collection of wild lilies Lilium, Trillium and Allium.

Alpine plants

Alpine plants and other low-growing perennials are exposed in the Rock Garden. This collection has been maintained in the Botanical Garden already since 30ties of the 20th century, whereas in the time period from 1953 to 1962, new geographical mountain collections were established - e.g. from Carpathia, Balkan, Caucasus, Pyrenean and Himalaya regions.

More than 500 taxons of these collections are distributed on a stony ground on terraces and retaining walls in the full sun or half-shade, as well as along shady, waterside and pond areas for moisture loving plants. In the alpine garden and on xerophyte terraces sun-loving plants like Sedum and Sempervivum are growing, while moisture-loving plants like Dactyorhiza, Mimulus, Leucojum and Primula occur along the pond.

Dahlias

Development of the Dahlia Garden in the Botanical Garden of the University of Latvia was dated already in pre-war years. From 1947 to 1963 dahlia collection was maintained by horticulturist Ernests Palcers. Later the curator of the collection was breeder Kārlis Ruks who selected more than 100 new varieties. For the present there are around 260 varieties in the Botanical Garden, and they represent all of 14 different dahlia flower types - single flowered, anemone flowered, collerette, waterlily, decorative, ball, pompon, cactus, semi-cactus, miscellaneous, fimbriated, star, double orchid, and paeony flowered dahlias.
