Biennial Plants with Yellow Flowers
Ornamental Biennials with Gold Blooms for a Yellow Theme Garden
Jul 31, 2008
A yellow flowering garden provides a splash of warm color to the landscape and no garden is complete without the long-last blooms, and ready self-sowing of biennial plants.
Foxglove Plants With Golden Flowers - A favorite biennial plant for the garden, there are several foxglove cultivars with yellow blooms.
- Digitalis grandiflora (Yellow Foxglove) has pale yellow, tube shaped flowers with brown speckles in the throat of the blooms. 'Carillon' is a dwarf form that reaches only 12-15 inches tall and has soft yellow flowers that combine well with other plants in the mixed border.
- Digitalis purpurea 'Primrose Carousel' (Primrose Carousel Foxglove) is a creamy yellow blooming form of the purple foxglove and has a long, blooming season.
- Digitalis lanata 'Spice Island' (Grecian Foxglove) is an orange-yellow colored foxglove that grows up to 4' tall and is said to be evergreen in warmer zones. Gardeners can expect this cultivar to provide weeks of flower color and then months of foliage color.
Yellow Blooming Hollyhocks
- Chater's Double Yellow - A tall biennial, this hollyhock will grow 6-8' tall providing a stunning backdrop for a yellow themed garden. The hollyhock flowers are ruffled and doubled with a soft yellow color that combines well with other plants in the gold garden.
- Summer Carnival Yellow - Part of the Summer Carnival Series, this double yellow hollyhock was an All-American Selections Winner in 1972 and has brighter gold flowers than 'Chater's Double Yellow' as well as being a bit more compact at only 3-5' tall.
English Wallflower (Erysimum cheiri) - Zones 5-9. This beautiful biennial is a native wildflower that does well in full sun to part shade and has bright gold flowers mid-spring through mid-summer. These English natives are becoming more popular in gardens worldwide for their bright blooms and sweet fragrance. Add wallflowers to your yellow themed garden to attract butterflies, bees and song birds. Like the Digitalis plants, all wallflower plant parts are poisonous so take care when using in a garden with pets and children. Most wallflower plants grow about 2' tall but the 'Tom Thumb' series is more compact and grows only 9 inches tall.
Blanket Flower or Indian Blanket (Gaillardia pulchella) - Usually blanket flowers have maroon or rust color petals but 'Torch Yellow' is a cultivar with bright gold, double blooms. Like most blanket flowers, 'Torch Yellow' is semi-drought tolerant and does well in containers because of its tolerance for poor soil conditions. These yellow blooms will attract butterflies and birds to the yellow themed garden for most of the summer and well into the fall. 'Torch Yellow' is only about 18 inches tall and a great, compact perennial for the garden. 'Yellow Plume' is another cultivar that has similar yellow blooms with double form but grows 2' tall.
