1. Lavender

Botanical name Lavandula
Plant type Perennial herb
Hardiness Zones 5–9

Lavenders are gorgeous perennial herbs that thrive in well-draining soil. They enjoy soil that is almost sandy, moderately fertile, and alkaline. While these plants thrive in alkaline soil, they can survive in neutral or slightly acidic soil too. Since Lavenders are native to the Mediterranean, they thrive in the sun’s full exposure throughout the day. An essential step is to grow in soil that has excellent drainage properties.

2. Mums (Chrysanthemums)

Chrysanthemums are lovely plants that can survive in almost any type of soil and still give magnificent flowers. Overall, these plants adore basking in full sunlight exposure, around 6 hours a day. They prefer soil that has excellent drainage properties and consistent moisture. While these flowering plants love alkaline soil, they will provide excellent results when topped off with natural compost or peat moss, creating a neutral environment for them.

3. Daylilies

Daylilies are another flowering plant that needs plenty of natural sunlight to be as healthy as possible. Soil type is less important to them, although heavy soil and sandy soil are a preference. The soil needs to have excellent moisture-retaining properties and a slightly alkaline pH level. They enjoy it when the soil has good drainage, but a lack of this feature won’t affect their growth too much.

4. Yarrow

Parsley loves alkaline soil, although it mainly thrives with the soil’s pH level between 6.0 and 7.0.

8. Celery

Celery is another herbaceous plant, and similarly to parsley, it thrives in well-draining soil with a neutral to alkaline pH value. The soil needs to be rich in organic matter, such as compost, manure, or leaf mold. Moisture-retentive soil is best because celery doesn’t enjoy dry conditions.
