Lavender is a sun-loving garden herb. It can be grown in a very sunny window for a while, but it is happiest outdoors in a pot or bed with excellent drainage.

Is a lavender right for you?

It suits you if you can give it full sun: 6+ hours and you are happy to water when the soil is dry 1-2 in down; never soggy. Difficulty: Challenging. It is toxic to cats and dogs, so keep it out of reach or choose a pet-safe plant instead. Not sure? Try the Plant Finder.

Similar plants to consider: Peace Lily, Philodendron Birkin, String of Pearls, Jade Plant.

Size and age buying guide

Younger or older plant? A younger, smaller plant costs less and settles in easily; an older, larger plant gives you the look straight away but costs more to buy and ship. With a moderate growth rate and a mature size of 1-3 ft, buy close to the size you want.

Sizes and what you will receive

Online shops sell plants by nursery pot diameter: about 4 in (small, shelf), 6 in (desk or table), 8-10 in (small floor plant) and 12 in and up (floor statement). Height varies a lot within one pot size, so read the listed height too. A mature lavender can reach 1-3 ft and growth is moderate, so a smaller plant will take time to fill out; buy closer to the size you want.

What to check when buying: a healthy lavender

• Firm, evenly colored leaves with no mushy stems at the soil line.
• Soil that is not sour-smelling or waterlogged when it arrives.
• No webbing, sticky residue or tiny moving insects under the leaves.
• Roots, if you peek, that are pale and firm rather than brown and soft.

Problems to know about before buying:

• Gray, leggy growth: Not enough sun.
• Wilting with wet soil: Root rot; lavender needs sharp drainage.
• Few flowers: Too little light.

What to check on arrival

1. Photograph the box and the plant before and while you unpack; most guarantees ask for photos.
2. Leaves and stems: firm, evenly colored leaves; no snapped stems or mushy tissue at the soil line.
3. Soil: not sour-smelling or waterlogged.
4. Pests: no webbing, sticky residue or tiny moving insects under the leaves.
5. Size: compare the pot size and height with the listing you ordered.
6. Report problems quickly under the shop’s guarantee.

Problems that often show up after delivery:

• Gray, leggy growth: Not enough sun.
• Wilting with wet soil: Root rot; lavender needs sharp drainage.
• Few flowers: Too little light.

Prices

We do not quote prices until we have checked them. They change with pot size, season and sales. To compare fairly, compare the same pot size and check whether a decorative pot and shipping are included.

Shipping and seasonal risks

A freeze in a cold delivery truck can damage it. In winter, order from a shop that adds heat packs or holds shipments in freezing weather, and bring the box inside as soon as it arrives. Summer heat in a delivery truck can also damage plants, so avoid long weekends in transit.

Your first week after delivery

1. Unbox right away and photograph any damage; most guarantees need photos within a set window.
2. Water only if the soil is dry; many plants arrive already moist.
3. Give it full sun: 6+ hours, but avoid harsh direct sun for a few days.
4. Keep it away from other plants for one to two weeks in case of pests.
5. Wait two to four weeks before repotting. Full care guide: Lavender care.
