#11 Cosmos
Cosmos is one of the easiest flowers to grow from seed. It prefers moist, well-drained soil that isn’t too rich, although it can grow in pretty poor soils too! Heat and drought tolerant, the cosmos can grow anywhere between 18 and 60 inches tall depending on the variety.
#12 Nasturtium
The quick growing and colorful nasturtiums can be sowed directly into the ground. The only thing this low maintenance plant will ask of you is regular hydration, let the soil dry between waterings, although the plant shouldn’t be parched.
#13 Sweet Pea
The beautifully scented sweet pea makes a wonderful addition to any garden, particularly as it requires so little care once established. Sweet peas like cool, but not cold, temperatures with their heads in the sun and their roots in cool, moist, and alkaline soil.
#14 Bachelor’s Button
The Bachelor’s Button is low maintenance and thrives in poor, dry soil. Plant it in a position where it’s sure to receive morning sunlight, but partial shade during hot afternoons. It doesn’t require too much in the way of watering, it becomes weak and floppy in soggy soil, and can also suffer stem rot and mildew.
#15 Californian Poppy
Californian poppies are beautiful bright annuals in reds, oranges, and yellows, which thrive in poor, dry or sandy soil and full sun.
#16 Marigold
Marigolds are so very easy to grow. They grow quickly from seed. Sow them directly after the last frost in full sunlight (or up to a maximum of 20% shade). They are tolerant of dry, sandy soil, but don’t like to be overly damp.
#17 Morning Glory
This plant is a hardy, quick-growing that requires little care! These annuals are self-seeding so you can enjoy them for years to come with minimal effort on your part. Perfect for covering walls and trellis, these beautiful purple, red, pink, or blue flowers flourish in full sun and moist, well-drained soil.
#18 Dahlias
Dahlias thrive in most climates although they don’t do so well in extremely hot and humid regions. They like sunny positions, particularly morning sun, growing more blooms with 6 to 8 hours of direct sunlight daily. They grow well in rich, well-drained soil with a slightly acidic pH.
